Answer
The total number of songs for each session is as follows:
Session A: 88 704
Session B: 88 706
Session C: 88 705
The increase can be calculated as:
extIncrease=(88706−88704)+(88705−88706)=2−1=1
So, the net increase in the number of songs streamed is 1 song.
Step 5
Determine, as a unit ratio, in the form 1 : ..., the number of paid users to the number of free users during session A.

Answer
In session A, the number of paid users is 690 160 and the number of free users is 8 120 031. The unit ratio can be calculated as follows:
extRatio=8120031690160
This simplifies to approximately 1 : 11.77.
